As a moderator PLEASE refrain from the use of profanity on this site.
Tid- It is clear that you do not know much about neonatal physiology. Babies recieve oxygenated blood from their mother through the umbilical cord until the moment of birth. At birth, the baby inhales air into the lungs for the first time, and oxygenation immediately switches from a blood-to-blood connection throught their mother to an air-to-blood process that the baby will use for the remainder of its life. Concurrent with this remarkable process, a duct (the ductus arteriosus) in the heart closes. While the duct is open, the neonate's blood bypasses the neonate's lungs since they are unused in the womb. At birth, the intra-heart ductus closes, and the blood is immediately shunted through the newly functioning lungs for oxygenation.
Tid- It is not wise to assume others are ignorant, when your content knowledge on the topic is so thin. Please be considerate of other posters. Upon occasion, they might be deeper that you are in a particular subject.
